Assuming the piece is centered and faced off square, can you part
it off, turn it around in your 4 jaw and drill it from the other
end??
Chances are the center drill is smaller than the finished hole
and the hole doesn't care which way it was drilled, once it is
drilled through.
If that works, facing off the parted end (which is now facing the
tailstock) should finish the item unless I missed something in the
description.

?
Thought I was being clever this time and started
turning a piece on a long hunk of 2" stock - so I'd have
plenty of margin for error.? See photo: ?
Next step is to drill a hole through the center of
the turned section, starting from the tailstock end.?
Unfortunately, in my cleverness, I didn't account for
the length of the chuck and the drill - I either need a
longer lathe bed or a shorter set up.
So, the next step now is to cut off the turned
section and re-mount it in my chuck.? Which leads to my
question.
I've gotten pretty good at centering a piece in my
4-jaw chuck, using DI.? But, in this case, I need to
center the counter sunk hole (where the tailstock is
currently mounted) and also make sure the axis of the
hole I drill will be parallel with the axis of the
turned portion (IOW, make the axis of the turned portion
parallel to the bed).? The turned down portion is about
2" long, so if it is not aligned parallel with the bed
the hole will be off by quite a bit.? Any advice on the
most efficient way to achieve this alignment?.
